Oglaf is basically the NC-17 OOTS/Discworld, although of a somewhat lower tier. I actually look forward to it all week. The artists batting average is better than almost any other webcomic for me.
QC is essentially a 2 Broke Girls or Don't Trust The B*** in comic form (with robots). Bickering humor about half the time. Bickering humor dates back to The Honeymooners. Hell, bickering humor dates back to Much Ado About Nothing. By comparison, there aren't many places you get owlbear jokes, or gay Conan jokes. So Oglaf has a lot more novelty.
